I just set up mprime to run on a Linux (Stampede) box with a Pentium 200 cpu. Every time mprime tries to contact IPS, it receives "PrimeNet error 1". The internet connection runs through a proxy server running on a WinNT machine with a dialup modem. I can switch the network cable from the Linux machine to a Win95 machine which has the same proxy assignment in the primenet.ini file and the Win95 machine has no trouble communicating with IPS. What might I be missing?
